This invention relates to advertising devices of that type employing an endless band carrying information and adapted to be passed behind a sight opening so that said information can be made to appear in the sight opening in such order and for such periods as may be predetermined.

The object of the invention is to provide improved means for operating said endless band, or to fit same in a casing wherein there is mounted a roll of paper, the holder for the latter being geared with the endless band, so that the action of drawing and detaching a section of paper from the roll causes movement of the band behind the sight opening to eiiect a change in the matter capable of being viewed through said opening.

According to the invention the improved device is characterized by the provision therein of a rocking frame in which a roll of paper is mounted and held against turning movement in said frame, the free end of the paper being left hanging from the device While an endless band carrying matter to be displayed is adapted to be passed behind a sight opening upon movement of the rocking frame in one direction; gearing between said rocking frame and a band driving roller including free wheel mechanism which permits reverse movement of said frame without operating the band driving roller.

Other features are also comprised in the invention which will however, be more particularly described with the aid of the accompanying drawings in Which:-

Figure 10 a plan view of the paper holder frame, a i

Figure 11 a longitudinal section of the sprocket roller for operating the endless band and Figure 12 a detail View showing the check plate mounted on said sprocket roller.

The device comprises a casing 1 containing a glass closed opening 2, through which advertising matter placed on an endless band 3 is adapted to be displayed, said band passing between the glass whichpcloses said opening 2 and a partition 4 within the casing, there being provided behind said partition l a storage space 3 for the band 3 except that portion thereof located between the glass and the partition s and the portions of 7 the band 3 adjoining the portion being displayed.

At the bottom of the partition 4 there is mounted a sprocket roller 5 around which the band 3 passes, the latter containing perforations which are engaged by the teeth 5a of the sprocket roller 5, so that when the latter is given turning movement the band 3 is positively driven.

The roller 5 is adapted to be operated, as will be hereinafter described, to draw vthe band 3 downwards behind the'glass closed opening 2, a guide plate 6 leading said band 3 to between the glass and the partition 4, while upon leaving the sprocket rollerfi, the band 3 is passed between a curved shield '7 which conforms to the shape of the sprocket roller 5, vand a guide plate 3 into the storage space 8, wherein it folds on the bottom 8 to said space, to be ultimately drawn from the top of same, over the guide plate 6' to be repassed between the glass of the sight opening 2 and the partition 4.

In order to keep the band 3 properly engaged on the teeth 5 of the sprocket roller 5, there is provided an idle roller 9, which is kept pressed by springs 10 against said roller 5, the band 3 passing between the rollers 5 and 9, the latter of which contains circumferential grooves 9 to take the teeth 5 of the sprocket roller 5.- i

The sprocket roller 5 is operated intermittently to pass'the band 3 downwards behind the sight opening2, by the action of drawing a length of paper from a roll. 11 thereof mounted at the bottom of the device. 7

The roller 11 has inserted therein a core 11, having a diamond shaped cross section, the ends of the core 11 being fitted with metal end plates 12, and being mounted across a U shaped rocking frame 13, the legs of which are fitted or are attached to and turnable with short spindles 14 .journalled in the side walls of the casing 1,

while the upper edge of the cross portion of said U shaped frame is provided with serrated cutting edge 13 The spindles 14 are short sections of tubing containing opposed slots in their inner ends, into which slots, cross bars or projections 13 on the frame '13 are forced.

One of the spindles 14 has attached thereto the inner end of a coiled spring 15 located within a housing 16, the other or outer end of said spring 15 being secured to said housing or the casing 1.

The other of the spindles 14 has fitted thereon and turnable therewith a ball clutch '17, while surrounding the latter is a toothed wheel 18,'

which meshes with an idle toothed wheel 19, in turn in mesh with a further toothed wheel. 20 on the spindle of the sprocket roller 5.

The balls 21 of the clutch 17 are held in inclined recesses 21 in the periphery of the latter, so that upon the spindle 14 and clutch 1? being given turning movement in the direction indicated by the arrow in Figure 6 of the drawing, the balls 21 tend to become jammed between the clutch 17 and the toothed wheel 18, and cause the latter to turn with the clutch 1'7 and the spindle 14. When the clutch 17 is given turning movement in the reverse direction to that indicated by the arrow in Figure 6, there is no tendency for the balls 21 to become jammed between the clutch 1'1 and wheel 18 and consequently said clutch and its associated spindle i i are free to turn without the wheel 18. The clutch 17 there foreyprovides freewheel mechanism between the frame 13 and the gear train to the band driving roller 5.

Means for facilitating the insertion of the core 11 in, and its removal from the Ushaped frame 13, comprise on the inner side of each leg of the latter, a pivoted plate 22, and a sliding plate 23, containing opposed'recesses 22 and 23 respectively, which, when said plates are positioned as shown in Fgure 9, accommodate and retain an endof the core 11 The frame 13 is slotted to take pins 24 on the plate 23, the latter being normally pressed by a spring 25 towards the plate 22, which uponv the plate 23 being moved against its spring 25 and away from the plate 22, is capable of being swung on its pivot to the position shown in Figure 8 to enable a core 11 to be inserted in or removed from the device, a stop 26 limiting outward movement of the plate 22. y

In order to permit only a single revolution at one time of the sprocket roller 5, which is of a diameter such that one turn of said roller will bring about a change of matter on the band 3, to be displayed through the sight opening 2, the sprocket roller 5, has secured to .one end a circular plate 27 with a stop 28 thereon, while a bell crank lever 29 carrying a pin 30 at one end is mounted, so that the latter .is capable of engagement with said stop 28, the other end of said .lever .29 being positioned in the path of travelof a projection 31 from the spindle 14 carrying the clutch 1'7 and wheel 18. I

Normally the bell crank lever '29 is held against the action of a spring 32, by the projection 31, so that the pin 39 is clear of the stop 28 but upon the spindle .14 being turned in the direction indicated by the arrow in Figure 4 to cause the projection 31 to clear the end of the lever 29 and following the stop 38 passing from below the pin 30, the latter is by the action of the spring 32 'on the lever 29, forced on to the periphery of the circular "plate 27, in readiness for engaging the stop 28, when the sprocket roller 5 has made one complete turn, whereby the travel of the band is stopped. Immediately following the stopping of the band 3, the projection 31 on the spindle 14 again engages the lower end of the bell crank lever 29 and lifts the pin 30 on the upper end of said lever 29 from engagement with the stop 28, leaving the roller 5 free to be given another complete turn per medium of the gear wheels 18, 19, 20 when required.

In order to minimize shock likely to be caused by the stop 28 striking the pin 30, there is provided a'spring 33 adapted to be engaged by the projection 31 as it comes round to engage the lower end of the bell crank lever 29, thereby bringing the mechaism to a standstill gradually instead of suddenly.

The casing 1 is formed with a downturned upper edge 1 adapted to be hooked over and behind the upper edge of a back 34, previously secured to a wall or other fixture by screws or other fastenings, so that when the casing 1 is in position on said back, 34, the fastenings are hidden and are inaccessible, the lower end of the casing 1 being locked to the back 34 by any suitable means, such as by a pad-lock engaged in a hasp or loop on the back 34 and upon which hasp or loop a slot in the casing l is passed.

The device is operated as follows:

The free end of the roll 11 of paper hanging from the bottom of the device as shown in Fig ures 1 and 2, is gripped and pulled downwards, the operation imparting approximately half a turn to the roll 11 and the U-shaped frame 13 against the action of the spring 15. This brings the cutting edge 13 of the frame 13 over and 110 into contact with the paper just about where it leaves the roll, so that the unrolled section of paper held in the hand can by being given a twisting or tearing action be detached from the roll 11. 115

When the roll 11 andframe 13 are turned forwards by the pull on the free end of the paper, turning movement is imparted through the clutch 17 and wheels 18, 19 and 20 to the sprocket roller 5, as before described to move the band 3, and effect a change of matter in the sight opening 2.

Following the section of paper being detached from the roll 11, the latter is returned by the spring 15 to the position shown in Figure 2, with- 125 out operating the wheel 18, inside of which the clutch 17 turns, and upon said return operation being completed, the new end of the paper dropsand hangs from the roll 11 in readiness to be gripped, for the next operation of the device.
